## Topics Covered in Exercise 12.3 Class 8 Mathematics Questions

eSaral’s subject experts of maths have some significant topics related to ex 12.3 class 8 maths which are explained here in detail format.

 1 Division of Algebraic Expressions Division of a monomial by another monomial Division of a polynomial by a monomial 2 Division of Algebraic Expressions Continued (Polynomial ÷ Polynomial)
1. Division of Algebraic Expressions

Division is the inverse operation of multiplication.

A. Division of a monomial by another monomial

• First write the irreducible factors of both monomials.

• Eliminate the common factors.

• The balance is the solution to the division.

B. Division of a polynomial by a monomial

• For both polynomials and monomials, write the irreducible form.

• Take out the common factor from the polynomial.

• Eliminate the common factor if possible.

• The balance will be the required answer.

2. Division of Algebraic Expressions Continued (Polynomial ÷ Polynomial)

For a polynomial, we reduce the polynomial and find the factors by using  identity or by finding common terms or by any other factorization. Then eliminate the common factors and the remainder becomes the required answer.
